FEED-WATER HEATER.

SPEGIFIUATEON formingpart of4 Letters Patent No. 719,229, dated January 27, 1903.

Application filed July 3, 1901. Serial Il'oA 66,947. (No model.)

transverse boxes or chambers connected withV said tubes at the upper and lower ends thereof, said parts being assembled to form a battery, a number of which is employed, one being connected with the other in such manner that the feed-water is compelled to flow from the upper part of one battery to the lower part of the adjacent one and in the direction contrary to the products of combustion from the boiler-furnace, whereby water that is at the point of its highest temperature in each battery or series is conveyed from that battery to the part of the adjacent one where the water is at the lowest temperature, and so on to the boiler, thus effectively heating the water.

Figure l represents a longitudinal section of a feed-water heater and fuel-economizer embodying my invention. Fig. 2 represents a transverse section thereof on line c Fig. l. Fig. 3 represents a longitudinal section of a modiiication. Fig. e represents an end View thereof.

V4Similar letters of reference indicate corresponding parts in the iigures.

Referring to the drawings, A designates a series of vertically-arranged tubes which rise from the transversely-extending cylinders orA boxes B and are connected at top with the transversely-amanged cylinders or boxes C. Below the boxes B is the manifolding-pipe B', between which parts are the branches or necks B2, which form communications between said pipe and boxes. Above the boxes C is the manifolding-pipe C', between which parts are the branches or necks C2, whichA form communications between said pipe and boxes, al1 of said parts being properly bolted or otherwise secured and constituting a section. A number of sections thus formed produce batteries, the adjacent ones of which are connected by the pipes D, it being noticed that each pipe extends from the upper pipe C' of one battery to the lower pipe B of the adjacent battery,whereby water is caused to circulate from one battery to the other, it being noticed that the lower boxes of the first battery are provided with the feed-pipe E,the operation being as follows: The water enters the lower manifolding-pipe B' through the inlet-pipe E,passes through the necks or pipes B2, and enters the boxes B, and from then ce it enters the vertical tubes A, where it becomes heated and enters -the upper boxes C and passes through the necks or pipes U2 and enters the upper manifolding-pipe C, after which it reaches the circulating-pipe D and is directed by the saine downward to the lower manifolding-pipe of the adjacent battery, from whence it again rises into the upper manifolding-pipe of the second battery, whereby it is still further heated, after which it descends to the third battery, where it is again further heated, and so on to the boiler, it being seen that the feed-water is compelled' to pass in a devious course through each battery in a direction contrary to that traversed by the products of combustion from the boiler tothe chimney, whereby the water is edectively heated, the products of combustion-of the boiler-furnace being utilized for that purpose.

The Vlower manifolding pipes B are of somewhat larger diameter than the,` upper ones and conical in shape, thus forming chambers where the feed-water may come to 'rest and deposit impurities contained therein, said pipes having at their largest ends the closures F, which are held in place by bolts or other means, adapting the same to be removed for admission to the interior of said pipes, dac., for blowing outsediment.

G designates a blow-od pipe which may be employed.v In Figs. 3 and 4 I show vertical tubes A' terminating at top and bottom with the horizontal boxes or chambers H. At intervals said boxes are divided by the diaphragms J, thus interceptingthefiow of the feed-water.

At the end of each section are liues or passages K, which communicate with the top chamber of one section and the bottom chamber of the adjacent section, by which provi- IOO sion the water from the bottom chamber ascends the Various tubes A and enters the upper chamber H and is deected by the diaphragms J'into the passage K and so directed to the bottom chamber of the adjacent section.

Havingthus described myinvention, what I claim as new, and desire to secure by Letters Patent, is-

l. In a feed-water heater and fuel-economizer, batteries, each composed of a series of Vertical tubes, longitudinally and transversely extending communicating boxes atthe t-op and bottom thereof, a manifoldingpipe communicating with the bottom box, and a Water-supply, a manifolding-pipe communicating with the upper box, and a conveying-pipe leading from the upper inanifoldingpipe of one battery to the lower manifoldingpipe of the adjacent battery.

2. In a feed-water heater and fuel-econo- Amizer, a battery, each section of which is composed of a series of Vertical tubes, boxes at the top and bottom thereof, horizontal jacent battery.

tubes extending from one box tothe other and forming communications between the several boxes respectively at the top and b ottom, a manifolding-pip'e communicating with one of said boxes and a Water-supply, and a manifolding-pipe communicating withthe other box, in combination with a conveyingpipe leading from the upper box of one section to the bottom box of the adjacent section.

3. In a feed-water heater, batteries each composed of a series of tubes, distributingboxes at the opposite ends thereof, necks connected with said boxes, manifolding-pipes connected with the respective sets of' said necks, a supply-pipe for one of said manifolding-pipes, and a discharge-pipe for the othei` manifolding-pipe,said discharge-pipe extending downwardly from the upper manifold of one battery to the lower manifold of the ad- HENRY G.
